入选标准
- •Age ≥60, male or female; (2) Patients with severe or above secondary tricuspid regurgitation (TR≥4+) (secondary tricuspid regurgitation: tricuspid regurgitation caused by right atrial disease, right ventricular cardiomyopathy, right ventricular myocardial infarction, left heart valve disease, congenital heart disease and other diseases); (3) A multidisciplinary cardiac team consisting of cardiovascular physicians, cardiovascular surgeons, imaging physicians, anesthesiologists, and at least 2 physicians considered the subjects to be at high risk for surgical procedures, i.e., EuroScore II was greater than 3.0%; (4) Left ventricular ejection fraction LVEF≥30%; (5) The subject voluntarily participates in the clinical trial and agrees or his guardian agrees to sign the informed consent; (6) Symptoms of tricuspid regurgitation, such as chest tightness, asthma, shortness of breath, lower limb edema, ascites; (7) NYHA Grades 2 to 4, including Grades 2 and 4; (8) The optimal drug treatment for tricuspid valve ≥ 30 days and the patient's state was stable; (9) Patients with mitral regurgitation, atrial fibrillation, coronary artery disease, and heart failure should be treated for ≥ 30 days with medication or ≥ 30 days after instrument therapy and in stable condition.

- •persons addicted to alcohol, drugs or drugs;
- •Patients with cognitive impairment;
- •A history of epilepsy or mental illness with primary and persistent seizures and poor drug control;
- •Participate in any other clinical trial (other than a registered study) within 30 days prior to signing the informed consent;
- •have had a pacemaker (other than a leadless pacemaker) or a defibrillator implanted in the past, or plan to have a pacemaker (other than a leadless pacemaker) or a defibrillator implanted;
- •tricuspid stenosis;
- •Ebstain syndrome;
- •esophageal esophageal echocardiography (TEE) and Trans thoracic echocardiography (TTE) were not esophageal esophageal tricuspid ring anatomy;
